Tire technology improves just like automotive technology, and frankly those of us who raced on MXX3s have no desire to see them reappear. I would just call Jon B. , as he suggested, and get the best, newer generation tire you can, since you are asking questions that indicate you will be driving plenty of miles.

And just to add some fly in the ointment, the Joy of Cold Weather Compound Cracking <20* F: ( So much for a rogue sunny day drive on a crisp winter day your car having been pent up for weeks if not months.)

RANT:

Seriously? Should tires subject to cold weather compound cracking be DOT approved? How many people are aware of this phenomenon and what are the actual risks? GM is not warning you can die from these cracks in their bulletin. (I have run badly cracked tires on light trucks without issue. Then I see scrapping a 2-year old Michelin with light crazing.)

"The Pilot Sport PS2 is not intended to be driven in near-freezing temperatures, through snow or on ice."

Rival S 1.5:

"Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.

Flexing of the specialized rubber compounds used in Extreme Performance Summer tires during cold-weather use can result in irreversible compound cracking. While compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced."

Pirelli: ("lowers" the bar to 45*F)

"Pirelli's warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius), so the P Zero System tires, like all summer tires, is not intended to be driven in near-freezing temperatures, through snow or on ice.

In the Immortal words of Eric Cartman: "Screw you guys (tire manufacturers), I'm goin' home (with my cracked MXX3's). I got 2 sets of cracked rears. Lots of burn outs are planned to use them up so I can get some new tires that will crack (sarcasm).

Sorry, not sure what your actual concern is, since your posted information has been common knowledge with virtually all high performance tires for many, many years!! This does not just include what you are listing above , but all the 200 Treadwear Rated Street/Competition tires are recommended not to be driven under 40 degrees. Not sure what your purpose is , because I can't think of anyone who really wants to go back to the rock hard iceskates of old? We all own a very high performance machine, and if Porsche, Lamborghini, Maserati, Corvette , etc. go with the same type of tire/compound , that alone should settle the situation. No offense , but this is essentially a non issue to 99% of us , and so we miss a day or two of cool weather driving , pavement temperature is likely a bigger compromise?

OT FORMULA ONE: Cold Cracking: I'm guessing F1 uses tire blankets just for that purpose which is interesting because in 2021 blankets will be outlawed. They're also going from 13 to 18in rims - still 405's in the rear but a decrease from 305 to 270 in the fronts. Ever notice how stretched those tires are?

Looks like my choice would be the Pilot Sport A/S 3 all season tire (which they call a Ultra High Performance Sport Tire) with a 45k warranty.

Followed by the Pilot Super Sport summer tire @ 30k

Keep in mind the limitations in the bottom right:

"Some vehicles come from the vehicle manufacturer with “split fitments”– meaning different size tires on
the front and rear axles. Because these tires cannot be rotated as recommended by Michelin, the mileage warranty on each rear tire will cover half
the number of miles as the standard mileage warranty for that particular tire design"

Thanks didn't catch that about splits. However I was using the warranty just as an indicator of how many miles the tires are capable of. The 30k for the Pilot Super Sports is definitely not bad and did you notice the Cups aren't even listed on the page?

I was trying to find Michelin Warranties for the "vintage" tires like MXX3 and Pilot Sports.

I wonder what the "MX.." refers too? Given the current MXM4 and MXV4 models I wonder if the MXX3 was related? (Like "MX" Series: M4, V4, and X3 variants.
